Groomed for reducing unwanted common-mode noise signals on a power line, the company’s recently unveiled series of common-mode chokes comprise a total of 128 parts utilizing seven different mounting packages. The SPCM series covers inductance values ranging from 65.0 mH to 120 mH and current values ranging from 0.3 Adc to 30 A_rms. All employ a toroidal core construction and many incorporate a winding separation spacer that provides 1 mm to 3 mm of creepage distance for safety agency compliance. Pricing ranges from $1.39 to $5.67 each in production quantities. Prem Magnetics Inc., Johnsburg, IL. (815) 385-2700.
